System Identification

machine learning and neuroscience
system identification

Deep networks have set new standards for accurately predicting responses of neurons in visual cortex to arbitrary images. However, these models still do not account for all the explainable variability of the neuronal responses in primary visual cortex. We are building better models for the visual system of mice and monkeys that can accurately predict responses and their per trial variability as well as estimate the general state that the brain was in during presentation of arbitrary visual inputs.
